Method and device for detecting indoor distribution signal leakage

Disclosed in the present invention are a method and a device for detecting indoor distribution signal leakage, which comprises: obtaining a terminal measurement report from a base station, performing signal parsing; obtaining Measurement Report (MR) data; filtering invalid MR and generating neighbor cell pairs based on the filtered MR data, wherein, the neighbor cell pairs comprise information measured by a primary serving cell of the terminal and information measured by an indoor distribution cell, wherein, the primary serving cell is an outdoor macro-cell, and the indoor distribution cell is a neighbor cell of the outdoor macro-cell; determining whether the indoor distribution cell experiences signal leakage according to the record information of the neighbor cell pairs; calculating the direction of signal leakage of the indoor distribution cell. Therefore, it is simple and accurate to predict the indoor distribution cell which experiences signal leakage beforehand and perform adjustments in order to prevent the impacts on outdoor users.
